Is upper and lower curvatures are equal in symmetric airfoil?

(a) True

(b) False

I got this question in an internship interview.

This intriguing question comes from The Symmetric Airfoil in division Incompressible Flow over Airfoils of Aerodynamics

Best answer
The correct option is (a) True

Best explanation: The upper and lower curvature are equal in the symmetric airfoil because there is no maximum camber in the symmetric airfoil when compare to cambered airfoil it does not produce high lift, so these are used in the subsonic flights.
